Description

Generally known are the gates, consisting of 3 several panels, hingedly: they are interconnected and each can be pushed around its vertisal axis. With their horizontal alignment, these panels fold together with each other.

The invention relates to such kind of jurors and consists in the fact that the axes of the canvas and the supporting guide rails are inclined,; the purpose of facilitating the opening and clogging of the gate with the use of a pro- tive weight, and also with the aim of obtaining the ability to perform folding in a trapezoidal form, close to the form of the cross section of the slipway.

In FIG. Figure 1 shows the priler form of the invented gate (front view); FIG. 2-section ID AB in FIG. one; FIG. 3-section CD la fig. one.

The structure of half of the gate includes: not only panels. The extreme panels W have a width half as large as the lyrics of the majority of the panels; the middle of the cloth 8 has a leading edge 4, which is parallel to the axis of the first rotation. Zes from the gate is transferred to the base, horizontal forces (pressure 466)

tra) - partly on the base and partly on the hull. When opening and closing the gate, the panels perform a translational motion along inclined guide rails 2 and 5, simultaneously rotating relative to their axes /. The weight of the gate, directed parallel to the rails, is counterbalanced by a counterweight (counterweight) 9 placed inside the platform and connected to the gate by means of a cable 17 and the corresponding blocks. The counter-load during its movement slides along the guide rails 5, which at the top go somewhat steeper and at the bottom somewhat positioned in order to regulate the force of the counterweights on the gate as they open.

The axes of all panels are let through the gap in the floor under the gate. This slot should be closed when the gate is open. For this gap closure, a special device was used, consisting of ribbons 6, seated on guide rollers / 7, and one end tied to middle panels 8, and the other end to cable 7, which serves to close the gate with a winch J2. Cable 13 and a winch are used to open the gate. Axis / rotation
